Therefore, these products with defined 5' and 3' ends accumulate exponentially with each round of DNA amplification -- that is, for every n cycles of PCR there will be 2 -fold amplification of the specific DNA fragment.
1 By themselves, PVCâs do not present any problem.  Bigeminy, Trigeminy, Quadrigeminy, etc. - ventricular bigeminy is the occurrence of a PVC every other beat, trigeminy is every third beat, quadrigeminy every fourth beat. The main point with these types is that the PVCâs are more frequent in these circumstances. They are otherwise little different from PVCâs.
Atrial means the: top part of your heart. Ventricular means the bottom part of your heart. Bigeminy means every other beat is early. Since the electrical activity of the atrium is separated from the ventricle by the AV node it is potentially possible to have both atrial and ventricular bigeminy ...Read more.
